| Doc Text: |
A flaw was found in U-Boot. The bootloader fails to properly validate image sizes against partition boundaries when reading Android boot partitions. An attacker with physical access to the device can exploit this vulnerability by connecting crafted boot media with oversized headers, causing an out-of-bounds write into bootloader memory. On devices lacking Android Verified Boot (AVB) protection, this issue can result in memory corruption or a Denial of Service (DoS).
